wp_print_styles documentation? (1 post)

I'm planning to re-write a plugin I use and I want to include some CSS with the plugin so I don't have to modify the theme CSS file. I did some searches and I think I should use the call 'wp_print_styles' to add the CSS ... but unfortunately I can't find any documentation of this call.

Does anyone know where I can find this? (looking at the definition in source code didn't help me much unfortunately)
